reaction. >> the "pal" list is a good thing to know if you have a friend with food allergies to keep them safe. >> i think it's a good thing to tell kids. >> for heather's family, coping with food allergies has become second nature. her sister has them, too. heather has learned to plan ahead. she often brings her own food to school or to a performance. if she's going to a restaurant, she even has an information card for the chef. >> we might go out to eat, but i'll bring the allergy card. >> whenever she travels, she brings along her medicines. and she always has to be careful to avoid danger, even when working with another actor on a movie set. >> i had to kiss somebody, and i had to ask him before, did you have any peanuts today? and he said, "you know, i actually had this candy." and i said [chuckling] "you need to get some mouthwash." so, you know, we did that, and then it was fine. >> it was just a make-believe kiss for the camera, but it could have created real problems for heather. so remember, if you have any friends with food allergies, be a "pal." >> there's more "teen kids news" coming up next.
